4 of the 6 months he had an ERA under 3.00. June was 3.54. April they only struggle at 6.14.
From July on he lowwred his ERA and WHIP each month.
July: 2.25, 1.031
Aug: 2.12, 0.98
Sept: 2.06, 0.80
If we go strictly by ERA+ Bedard matched him in 2007. The laat time his season was topped was Mussina back in the strike shortened '94 season. He had a 164 ERA+ that year. From strictly an ERA+ perspective Im guessing its a top 10 season of all time. Will go check some of the other years from older pitchers
And April he missed time after taking that line drive off the foot.
